Atherosclerosis and CAD [PDF]

open access: yesEuropean Heart Journal, 2015
Atherosclerosis is the major disease process of cardiovascular medicine, leading to angina pectoris, myocardial infarction, and death. As stated many years ago by Rudolf Virchow, atherosclerosis is a chronic inflammation driven by cholesterol.1 With the introduction of statins2,3 guideliens from Europe and the USA4 strongly recommend their use in such ...

Detection of symptom-related coronary arteries in patients with coronary artery disease using real-time three-dimensional stress echocardiography with adenosine triphosphate

open access: yesИнновационная медицина Кубани, 2021
Aim 1) To develop normative values of global and regional left ventricular longitudinal deformation (LVLD) during real time three-dimensional stress echocardiography with adenosine triphosphate (ATP) and utilization of automated function imaging ...

High-sensitivity cardiac troponin T and copeptin assays to improve diagnostic accuracy of exercise stress test in patients with suspected coronary artery disease [PDF]

open access: yes, 2014
Background: The average diagnostic sensitivity of exercise stress tests (ESTs) is lower than that of other non-invasive cardiac stress tests. The aim of the study was to examine whether high-sensitivity cardiac troponin T (hs-cTnT) or copeptin ...

Cloud-to-end Rendering and Storage Management for Virtual Reality in Experimental Education

open access: yesVirtual Reality & Intelligent Hardware, 2020
Background: Real-time 3D rendering and interaction is important for virtual reality (VR) experimental education. Unfortunately, standard end-computing methods prohibitively escalate computational costs.

Using the distribution of cells by dimension in a cylindrical algebraic decomposition [PDF]

open access: yes, 2014
We investigate the distribution of cells by dimension in cylindrical algebraic decompositions (CADs). We find that they follow a standard distribution which seems largely independent of the underlying problem or CAD algorithm used.

A repository for CAD examples [PDF]

open access: yesACM Communications in Computer Algebra, 2013
Cylindrical Algebraic Decomposition (CAD, first introduced in [Col75]) of Euclidean space has become an important tool in mathematics and allows for practical quantifier elimination (QE) over the reals. Much research has gone into improving the projection operator (e.g. [McC85]), the use of partial CADs (e.g.

A co-analysis framework for exploring multivariate scientific data

open access: yesVisual Informatics, 2018
In complex multivariate data sets, different features usually include diverse associations with different variables, and different variables are associated within different regions.

Automatic CAD-model Repair: Shell-Closure [PDF]

open access: yes, 1992
Shell-closure is critical to the repair of CAD-models described in the .STL file-format, the de facto solid freeform fabrication industry-standard. Polyhedral CAD-models that do not exhibit shell-closure, i.e.

Hierarchical explicit–implicit combined sensing-based real-time monitoring method for the service performance of complex equipment [PDF]

open access: yesJournal of Intelligent Manufacturing and Special Equipment
Purpose – Real-time monitoring of the critical physical fields of core components in complex equipment is of great significance as it can predict potential failures, provide reasonable preventive maintenance strategies and thereby ensure the service ...
